tinc 1.1pre19 slower than tinc 1.0, experimentalProtocol even more
...throughput. Note, this is from memory, can't find my notes
unfortunately.
Reading about tinc 1.1, specifically the use of a GCM cipher suite to
reduce the cost of HMAC, we've decided to test it. The results are quite
surprising:
* using the experimental protocol, throughput falls to around 380Mbit/s;
both tincd are at or just above 100% CPU (the host has 8 cores)
* not specificing ECDSA keys, throughput is around 600Mbit/s; both tincd
are at around 90-95% CPU
